The method of controlling pest (hereinafter referred to as “controllingmethod”) can be carried out by treating a plant or the soil where aplant grows with an effective amount of a “carboxamide compound” and a“diamide compound”.

The part of plant to be treated is stem and leaf of a plant, seed orbulb of a plant, and the bulb means bulb, corm, rootstock, tuber,tuberous root and rhizophore.

In the “controlling method”, the treatment of a plant or the soil wherea plant grows with a “carboxamide compound” and a “diamide compound” canbe carried out separately at the same timing, but the treatment isusually carried out by using a “composition” in light of convenience.

In the “controlling method”, the treatment with a carboxamide compound”and a “diamide compound” is, for example, stems and leaves application,soil application, roots application or seeds application.

Examples of the stems and leaves application include a treatment forsurface of cultivated plant by a stem and leaves spray or a stem andtree spray.

Examples of the root application include a method of dipping a wholeplant or the root of a plant into a liquid containing a “carboxamidecompound” and a “diamide compound” and a method of sticking a solidpreparation comprising a “carboxamide compound”, a “diamide compound”and a solid carrier onto the root of a plant.

Examples of the soil application include a method of spraying a“composition” onto a soil, a method of mixing a “composition” with asoil and a method of irrigating a “composition” into the soil.

Examples of the seed application include a method of treating seeds orbulbs of a plant to be protected from a plant disease with a“composition”. Particularly, the application can be carried out byspraying a suspension of a “composition” to the surface of seeds orbulbs, or by spreading wettable powder, emulsifiable concentrate orflowable formulation itself or a mixture thereof with a small amount ofwater on the seeds or the bulbs, or by dipping the seeds into a solutionof a “composition” for a prescribed time, by film coating application orpellet coating application.

The amount of a “carboxamide compound” and a “diamide compound” used inthe “controlling method” is different depending on the kind of a plantto be treated, the kind of a plant disease to be controlled and itsfrequency, the kind of a formulation, timing of treatment, method oftreatment, place of treatment, weather condition, and the like.

When a “composition” is applied to stems and/or leaves of a plant or tothe soil where a plant grows, the total amount of a “carboxamidecompound” and a “diamide compound” is usually from 1 g to 500 g/1000 m²,preferably from 2 g to 200 g/1000 m² and more preferably from 10 g to100 g/1000 m².

When a “composition” is applied to seeds of a plant, the total amount ofa “carboxamide compound” and a “diamide compound” is usually from 0.001g to 10 g/1 kg of the seeds, and preferably from 0.01 g to 1 g/1 kg ofthe seeds.

An emulsifiable concentrate, wettable powder or flowable formulation isusually used by diluting the formulation with a small amount of waterand spraying the diluted formulation. In this case, the concentration ofa “carboxamide compound” and a “diamide compound” in total of thediluted formulation is usually from 0.0005% to 2% by weight andpreferably from 0.005% to 1% by weight.

A powder formulation or granule formulation and the like is usually usedwithout dilution.
